  • Flotation of mixed oxide sulphide copper-cobalt minerals

    Three cobalt-bearing oxide minerals are observed in the mixed ore, ie heterogenite, kolwezite and cupro-asbolane, while carrollite is the only cobalt-bearing sulphide mineral A two-stage rougher-scavenger flotation process is used in which sulphides are extracted from the ore first In the second stage, oxides are activated using controlled.
